This is a division of my patent No. 1,464,463, granted August 7, 1923,on an application Serial No. 253,314, originally filed September 9,1918.

This invention relates to a paper changing and printing press'plant.

The principal objects of this invention are to provide an arrangement ofa comparatively simple character by which a plurahty of web rolls can beheld in readiness for connection with the websothat a continuous supplyof web can be provided for a printing press or a plurality of printingpresses at different levels; to provide an arrangement for this purposeby means ofwhich one s de of each roll, (both new and old) will bereadily accessible; to provide a way by which new rolls may be carriedthrough a series of presses while they are running to 20 supply them toother presses on the line;to save room in height; and to so arrange theweb roll support with reference to the press that there will always be aspace at the end of the press through which a roll can bemoved'laterally.

Further objects and advantages of the invention will appear hereinafter.

Fig. 1 is a transverse sectional. elevation of a press room containing aplurality of presses and showing the layout oft-he press room in orderto apply this lnvention thereto. the paper roll supporting mechanismbeing shown diagrammatlcally;

Fig. 2 is an enlarged elevation of two sets of web rolls looking at themin the same direction as in Fig. 1, but showing the details ofconstruction in accordance with this invention; and

roll Fig. 3 is an elevation of the same taken from the side of the pressconstituting an end elevation of the Web rolls themselves,

The usual practice is to provide each paper roll with a spindle which isto be applied to the roll before it IS ready to be connected with theexpiring web. According to this invention this process is entirelyeliminated. thus saving time and expense, and the paper rolls aresupported on paper cones running freely on the ends of studs,one ofwhich can be forced into the open'end of the core so as to hold firmlythe paper roll in central position, means being provided for positivelytransmitting the rotation of the roll to the taper cones. These conestuds are supported on suitable bracket bearings which are mounted oncarriages. The carriages are provided with driven propellers mountedthereon, which may be thrown into contact with a paper roll supported bythe studs thereon. Thus, when one of the rolls is about to be exhaustedits carriage is moved along the tracks toward a fresh paper roll whichhas been pasted already, and is being caused to revolve at the properspeed by its own propellers. The fresh paper roll of course is mountedon a carriage like the eX- hausted one.

lVhen the tworolls contact the pasted end I the fresh roll is, ofcourse, carried along by the expiring web and at this moment a Thearrangement of the press room plant,

according to this invention, is such that these paperroll carriages canbe so located as to provide two free passages at either end throughwhich fresh paper rolls may be transmitted preferably on overheadcarriages or'cranes without interrupting the running of the press orpresses. For this purpose tworolls are provided for each press mountedhorizontally one above the other. Suitable platforms or galleries arearranged in such a wa 1 as to leave lull assa e-wa r on either side bywhich a fresh supply of rolls may be brought from storage. Thesepassageways are located one between the; system of carriages and the endof the press, and the other at the other side of the carriage. v

The relative locations of the elements of this'paper roll changingsystem is important. It is to be noted that a plurality of press frames.10 are indicated in their usual relationship to each other in the pressroom. This invention can'be applied to one or an desired number.

presses horizontally. The lower, tracks 12 provide for the applicationof the rolls to the lower decks of the presses, but if it is desired toapply them to the upper decks one or moretracks 13 above them areprovided for that purpose. Their cranes 11 take the rollsfrom the lowertrack and lift them to the higherone. It is to be noted that I haveshown two pairs of these tracks 12 and tracks 13 arranged in the sameway. This is to provide two horizontal passage-ways through which therolls are introduced into the space behind the presses and moved alongthatspace to the proper press. These may be called the front and rearpassage-ways, and are indicated fully in Fig. 3.

The rolls R, of'course, are supported by straps 14 and cables 15, theoperating mechanism for which need not be described in detail as anyconvenient well-known form The drums 16 carrying the cables can be movedcross ways on their carriages. The two passageways which have beenmentioned are located respectively one just at the rear of the pressframes and the other at the rear end of the space provided behind thepress frames. Between these two passage-ways is-located a supportingframe 20 for the old and new rolls for each press. One of these framesis provided for each four rolls in active service in the formillustrated, and it will be seen that the rolls R can be moved along thetracks 12 or 13 laterally with respect to the presses through freespaces or passage-ways in a horizontaldirection even while the pressesare running, and without interrupting their operating in any way and therolls brought up ad acent to the support 20 to which they Wlll beapplied, and also brought to the proper height. They can then be mountedon these supports in a manner to be described.

From what has been said and shown with relation to the layout of theplant, it will be seen that the paper rolls are changed horizontally,thus requiring less power, saving room and height, providing easyaccessibility to one side of each roll, and an also easy access to thenew rolls in addition to the provision of a clear passage-wayfor each ofthe rolls independently of the operation of the press. It is to be notedalso that the web WV passes beyond the crane carriage, the upper onepassing above it and the lower one below the space in which the rollsare brought in so that there can be no interference.

FiXedly mounted on the floor or any solid stationary supports are tracks21. On these tracks'run rollers 22. The rollers by means of legs 23which have flanges acting as ways slidingly support carriages 24. Thereis one of these carriages for each pair of legs.

These carriages carry brackets 25 for sup-;

The brackets 25 are held in place by bolts l3sliding in groovespreferably running the entire length. of the carriage 24 so that theycan move along these grooves .to accommo-r date the several widths ofpaper rolls.

Each carriage 24: is provided with a shaft having a hand wheel 46 andcarrying two pinions 4E7 meshing with two stationary racks 48 by whichthe carriages can be moved along the tracks 21.

Under the carriages are provided horizontal shafts mounted to turn infixed bearings. These carry sliding bevel gears 61 slidingly keyed tothe shafts 60, and meshingwith the bevel gears 63 on shafts journalledin bearings 64 fastened to the carriages. On each-shaft 65 are fastenedgears 66 which mesh with and drive gears 67 running loose on a propellerarm shaft 68. Each of these gears 67 meshes with a gear 69 fastened to apropeller shaft '70. This propeller shaft has bearings in arms 71 whichare fastened on the propeller arm shaft 68 and swing with it. On each ofthese shafts is of course one gear 59 and also one propeller wheel 72.In this way it wil be seen that the constantly driven shaft 65 operatedfrom any desired source of power constantly drives the propeller shaftsand consequently all the propellers.

When it is desired to throw the propellers into contact with a new webroll, this is done by operating a hand wheel 73 on a worm 74. Thisoperates a worm wheel 75 which meshes with this worm and also isfastened to the shaft 68. This shaft therefore is turned and thepropellers moved into contact with the new web roll or out of contactLet it be'assumed that in Fig. 3 the new roll- R has just been moved inon the right hand Fig. 3.

carriage 11 and set in the position B. When the other roll 1' is morefully exhausted its carriage 24 and supports 23 are moved sideways byoperation of the proper hand wheel 46 so that it comes over to aposition to the right of them shown at the top of The new roll It isrotating at web speed. The old web is brought into contact with it so asto take its free end with it as indicated. Then a severing knife isoperated to cut the old web and disconnect the old roll from the mainweb IV. Now the old roll spindle is removed and the carriage broughtback to its original position. The new roll R stays where it is firstplaced until it becomes almost exhausted.

From this it will be seen that the paper rolls are changed horizontally,thus saving room in height, that the rolls are all readily accessiblefrom one side, that power is saved because it is the light expiring rollthat is moved instead of the heavy new roll for purposes of paper changewhile the press is running, that passages are provided through 'whichthe new rolls may be carried through several presses while they arerunning for supplying some other press along a line and at the same timea continuous supply of web is secured to each press without the usualspindling of the paper rolls. Dispensing with this operation materiallyreduces the time and expense of attending to the change of the web.

Although I have illustrated and described only one form of theinvention, I am aware of the fact that modifications can be made thereinby any person skilled in the art without departing from the scope of theinvention as expressed in the claims. Therefore I do not wish to belimited to all the details of construction herein shown and described,but what I do claimis:

1. The combination with a series of printing presses, of a support for aplurality of web rolls spaced from the end thereof to permit new webrolls to be moved along transversely between the support and printingpresses while the latter are running, said support also having a spacebeyond it for a similar purpose.

2. The combination with a printing press, of a support for a pluralityof web rolls located at the end of the printing press, with a spacebetween the support and press to permit new web rolls to be moved alongtransversely between the support and printing press While the press isrunning, said support having means for holding rolls for an upper and alower deck, and means for guiding theupper web above, and the lower webbelow, said space for receiving the new web rolls.

3. The combination with a printing press,

of a support for a web roll located at the end of .the printing press,with a space between the support and press to permit new web rolls to bemoved along transversely between the support and printing press whilethe press is running, means for guiding the web above said space forreceiving the new web rolls, and a track at the top of said space butbelow the webv for supporting a web roll therein. 4. The combinationwith a series of printing presses, of a support for a plurality of webrolls spaced therefrom to permit new web rolls to be moved alongtransversely between the support and printing presses, said support alsohaving a space beyond it for a similar purpose, and transverse tracksfor roll carrying carriages located above said spaces.

5. The combination with a series of printing presses, of a support for aplurality of web rolls spaced therefrom to permit new web rolls to bemoved along transversely between the support and printing presses, aplurality of transverse tracks above said space and at different levels,and a roll supporting carriage mounted to run on each track.

In testimony whereof I have hereunto affixed my signature.
